Glass Bead

Glass bead is high-grade soda lime glass bead manufactured by the process of cascading a granulated soda lime glass powder or grain into a vertical kiln and then using the effect of softening the glass and gravity to cause the rounding of the glass grit or cullet. This technique has been refined to produce a sphere that is almost perfectly round, and in the reflective product, produces a prism that can have refractive indices as high as 2. Available in commercial, premium AMS and military specifications, conforming to AMS2431/6C and MIL-9954.

This media is also referred to as Beadomac.
